Figure QB1 shows a pin-jointed frame. The length of each of the horizontal and vertical members of the frame is 2m. The frame is supported by a HINGE at point A, and a simple roller support at point F. Two external forces are applied, one at point B and the other at point C, as shown in Figure QB14 Neglect the weight of the frame members. (a) Draw a free body diagram of the frame showing all external loads and supporting forces. (b) Calculate the magnitudes of the supporting forces at A and F.e (c) Use the method of joints to determine the magnitude of the forces in each of the following members of the frame: AB; AC; BC; BD; CD; CE. 4 State whether each member is in tension or compression. Clearly show all calculations. Be 2me De 2.5kN 2me 2m 2me Fe 2me E A 2me 6.3kNe Figure QB1e

System of Forces

A force is an external influence or agent that changes the state of a system. According to Newton's second law, the force applied to a body is proportional to the change in momentum of a body. Hence, whenever a force is applied to a body, its momentum changes. If the body is at rest, under the action of force, its state of rest changes to motion. In other words, the magnitude of the momentum of the body changes from zero to a measurable value. Similarly, if the body possesses some initial velocity, it has some associated momentum, the effect of force can cause the body to halt or come to rest, that is, the momentum reduces to zero.
